The power of the current Globalist incarnation of Empire rests on their control of the United States' stockpile of nuclear weapons, and their willingness to nuke the fucking planet if they don't get their way
The banking system is based on the U.S. Dollar. The U.S. Dollar is based on the Petrodollar system with Saudi Arabia, which means that the might of the U.S. military is what props up the Petrodollar. Holding up the U.S. military as a viable threat is the nuclear weapons stockpile, which the Globalists (using their agents in the military and government) wave around as a deadman's switch: You will take U.S. Dollars as we say, or EVERYONE DIES!
Well, since that works so well for the Globalists in keeping their banking system of predatory bullshit going, they're using it as the final trump for every last challenge they face, and they make that threat implicitly with weasel words about World War 3. That's the basis for so much arrogance in Globalist circles, thinking that nothing opposing them can endure and therefore it is only a matter of time before final victory is theirs.
They're not wrong. The fear of all life on Earth burning up in nuclear fire, or dying of cancer due to radiation poisoning, or suffocating in the dust, or freezing to death in the winter that follows, or starving to death, or by exposure, is in itself rational; what isn't is the fear that these Globalists have the weapons on lockdown or that they have the nerve to go through with it.
They don't. This planet is all they have--stories about NASA, secret space programs, etc. notwithstanding--and if they nuke it, no amount of Deep Underground Military Base preparedness will preserve what they value from destruction. They know that (as a class), and they're counting on enough of us shitting ourselves to never call their bluff.
Because that is what it is: a bluff. So long as you leave them an out, they will never go through with it; you can mop them up later, so ensure that this out splits them up and isolates them for easy pick-offs. You've got to neutralize that deadman's switch if you want them gone. Deal with that threat to your future and you'll end Empire for good.
